我该如何解决这个问题我已经安装了 Microsoft C++ buildtools 并尝试使用 pyqt5 轮文件下载它（给我一个这个文件不是这个平台上支持的轮子

Answer 1

请尝试：

1. 从页面https://pypi.org/project/PyQt5/#files下载文件 PyQt5-5.15.4-cp36.cp37.cp38.cp39-none-win_amd64.whl

2. 将其重命名为 PyQt5-5.15.4-py3-none-win_amd64.whl

3. 运行 pip install PyQt5-5.15.4-py3-none-win_amd64.whl

我能够将它安装到 Python 3.10 虚拟环境中，然后能够从https://zetcode.com/gui/pyqt5/firstprograms/运行示例
